Finnish PM Sanna Marin has said Europe is "not strong enough" to stand up to Russia's invasion of Ukraine on its own, and has had to rely on US support.

 

During a visit to Australia, the leader of the pending Nato member said Europe's defences must be strengthened.

 

"I must be brutally honest with you, Europe isn't strong enough right now," she said. "We would be in trouble without the United States."
